IMPROVEMENT IN SHOE-SCALLOPING MACHINES.

Specification forming part of Letters Patent No. 212,718, dated February25, 1879 application filed December 27, 1878.

- To all whom it may concern:

Be it known that I, WILLIAM MANLEY, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Shoe-Scalloping Ma chines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art toavhich it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to shoe-scalloping machines, and is designed toprovide mechanism adapted to adjust and hold securely the button-fliesof ladies, misses, and childrens shoeuppers in proper position, wherebythe same may be scalloped with uniformity and dispatch, cutting from oneto twenty pieces at a sii'lgle operation.

The invention consists, first, in the combination, with a presserbar andmechanism adapted to cause the same to bear down upon the button-flies,of an independent adjuster adapted to be withdrawn from beneath saidbutton-flies when the latter are secured in position by the presserbar;second, in the combination, with a presser-bar and its lever, of anactuating-lever adapted to be operated by suitable treadle mechanism incausing said presser-bar to hold the button -flies upon a cutting-block;third, in the combination, with a presser bar, its lever, and anactuating -lever, of connecting mechanism adapted to cause the same tobe moved together in forward or rearward movement upon a suitablesupport; fourth, in the combination, with a horizontal slotted arm, of apresser-bar lever and an actuating-lever, the two respectively pivotedupon bolts which work transversely in said slotted arm; fifth, in thecombination, with a presser-bar formed with upright thimbles, ofdownwardly sprin g-pressed pins working in the latter; sixth, in thecombination,

Referring to the drawings, Figure l is a view, in perspective, of amachine embodying my invention. Fig. 2 is a view of the machine properdetached from a supporting-stand, the same being shown with both thecutting-block and the plate upon which the latter rests removedtherefrom. Fig. 3 is a similar view, but with the plate upon which thecuttingblock rests in position upon the vertically-adjusting screws.Fig. i is a detail sectional view through line m y of Fig. 3. Fig. 5 isa detail view of the cutting-block and plate upon which the same rests.Fig. 6 is a detail view of the adjuster. Fig. 7 is a view of mycutting-chisel. Fig. 8 is a view of the jack.

The horizontal slotted arm supports the presser-bar lever B and theactuating-lever G by means of bolts D, which latter work transverselywithin the slot of said arm, and are connected together by a plate,E, soas to have simultaneous and even movement either forward orrearward.Each of said bolts is formed with both extremities screw threaded, and

which, respectively, project out beyond the slot, and .are engaged withsuitable nuts-F F in clamping the levers to the machine. Each bolt isalso formed with a shoulder, f, against which the eye of thecorresponding lever has lateral bearing, while that portion, f, of thebolt-stem which is within the slot is made rectangular, so as to preventthe bolt from turning. By loosening nuts F said bolts are freed fromtheir clamped position within the slot, and can therefore be readilymoved in transverse line to and fro in the same, corresponding to theposition required of the press- .er-bar in holding different-sizedbutton-flies in position upon the cutting-block.

Presser-bar Gr is preferably formed curved, so as to be adapted to theform of the buttonflies, .and is provided with two upright thimbles, 9,within which work, respectively, the downwardlyspring-pressed pins g.Centrally between said pins the presserbar is provided with a tubularupright stud, a, formed with serrations .or notches on its upper.edge,-with which the extremity of the long arm of the presser-bar lever.en gages, corresponding teeth being formed .on said extremity, so as.to interlock with the teeth of said stud, and thus prevent thepresser-bar from being moved out of position relative to its angle withthe presserbar lever. A screw-bolt or other suitable fastenin g device,1), passes through a corresponding pertbration in said extremity of thepresser-bar lever, and engages with said tubular stud. The upper surfaceof the short arm of the actuatinglever engages with the under surface ofthe short arm of the presser-ba-r lever, and when in operation serves tohold said presser-bar securely down upon the buttonflies. An upwardly.sprin g pressed device tends to maintain the two levers freefrornengagemen-t with .each other, and hence, when the I actuating-leveris not operated by the treadle mechanism, the presser-bar isautomatically released from the position in which it clamps thebutton-flies upon the cutting-bed.

The particular form .of device used may be changed as desired, butpreferablyconsists, as shown, ofa vertical rod, 0 whose lower extremityworks within atubular standard, OZwhileits vertical body is incased by aspiral spring, 0 which latter engages therewith, .and serves to hold therod in raised position. Its upper bent extremity, 0, works within avertical slot in the machine-frame, and engages with the till der sideof the long arm of the actuating-lever.

A spiral spring, H, intermediately connects the extremity of the longarm of the actuatin g-lever with the pitman H, which latter connectswith any suitable foot-treadle.

The cutting-block K is preferably made of wood or equivalent lightmaterial, and is provided with a metallic mold, L, within which latter ametallic-composition bed, M, is incased. Said cutting-bed may becomposed of tin and lead, or any other analogous metallic substancescapable of answering the purpose in view. A plate, N, supports thecutting-block,

.moving out of position thereon.

and is provided with one or more pointed studs, n, which latter engagewith the under surface of said block, and prevent the same fromAdjustingscrews P, working in the platform of the machine, give verticalmovement to one or more cutting-block at any point thereof, as occasionmay demand. Sharp pointed pins may be formed on the working end of theadj ustingscrews, if desired, for purpose of securing the cutting-blockin position. When said block is drawn out on its supporting-plate it maybe maintained in working position by means of a suitable jack, R,provided with a flanged base,

which latter is fastened to the bench upon which the machine may rest.The verticallyadjustable screw 7' of said jack is provided with apointed stud or pin, 1", whereby the block is prevented from unduemovement.

The platform of the machine is provided with two fixed legs orstandards, S, in its forward part, and swinging legs or standards S,

pivoted, respectively, to opposite sides of the rear or farther part ofthe platform, said swin gin g legs being secured by nuts upon horizontalpivots, so as to have movement when unclampedin a vertical plane. Saidadjustable legs adapt the cutting-block to be moved in operativepositionas may be required under different circumstances. An adjuster, T, of anysuitable form, is preferably provided with one fixed upright, V, twomovable upright guides,

IV, and a spring-holder, Y. The button-flies,

in any suitable number from one to twenty,

are placed upon the adjuster together with the pattern. By means of themovable guides the :button-fliesare adjusted in position, and then thespring-holder secures the same. The adjuster, provided with thebutton-flies, is placed on the cutting-bed and beneath the presser.

The springpressed pins then press slightly upon the button-flyscallop-pattern and the button-flies over the open spaces formed in.

the adjuster, and the presser-bar itself does not yet bear upon thesame. When the adjuster is withdrawn by means of the actuating-lever andtreadle mechanism, the entire pressure of the presser-bar is exertedupon the button-fiies, and the number of pieces are held securely inposition until duly scalloped, which latter operation only requires afew seconds.

By this mechanism all work of this general character, from an infants upto a womans shoe-upper is accomplished with great rapidity anduniformity, while in changing from one style to another no expense isentailed, excepting such as is required in providing a few pieces ofstraw-board.

In connection with this machine I use a button-fly chisel, Z, especiallyadapted to cut the lower end of a button'fly in a ready manner.Heretofore such cutting has been done with a knife, or in the shape of apattern which shoecutters work by; but both of the above processes areslow and defective.

My chisel is formed with a long wing, 2,

made curved, as shown, whereby it is adapted to make the cut in anefficient and quick man- .ner. parts of the plate-body, so as to adjustthe The cutting-chisel shown in Fig. 7 is represented in the drawings,that the operation of the machine may be fully understood 5 but no claimis herein made to the same.
